WILLIAM J. GRO'IENHUIS, OF CHICAGO, ILLINOIS, ASSIGNOR 'I'O CUSHION-CORNER BED SPRING- CO., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

BED-BOTTOM SUPPORT.

To all whom it may concern Be it known that I, WILLIAM J. GROTEN' runs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bed-Bottom Supports, of which the following is a specification.

This invention relates to bed-bottoms of that general type wherein the bed-bottom frame is supported at its four corners on the side rails of the bed-stead frame through the agency of cushioning springs at the four corners which, at their upper ends receive the load of the bed-bottom frame, and attheir lower ends are stepped upon transverse supporting bars that span and rest upon the side rails of the bed-stead frame.

The main object of my invention is to effect an economy in the cost of transporting and storing such bedbottom frames, and this is accomplished by my improved con struction of transverse supporting member which enables two frames to be nested for transportation or shipment within a space but slightly exceeding the dimensions of a single frame.

Another object of the invention is to provide such a transverse supporting member as can readily be adjusted to slightly varying widths of bed-stead frames.

My invention, its advantages and its manner of use will all be readily understood when considered in connection with the accompanying drawing showing an improved mechanical embodiment thereof, in which,-

Figure 1 is a perspective elevation of a bed-stead frame and bed-bottom equipped with the device of my invention. Fig. 2 is a side elevation, enlarged and broken out between its ends, of my improved transverse supporting bar, the side rails of the bedstead frame appearing in cross section. Fig. 3 is a sectional detail on the line 33 of Fig. 2.

Referring to the drawings, 5 designates eachv of the head and foot pieces, and 6 the angle-iron side rails of an ordinary bedstead frame.

designates the end rails, 8 the side rails, and 9 the corner-connecting brackets of the bed-bottom frame, and 10 designates any suitable bed-bottom fabric stretched bet-ween the end rails 7 of the bed'bottom frame.

The bed-bottom frame here shown is elas- Specification of Letters Patent.

tically supported at its four corners upon cushioning-springs11 that are housed within loop-shaped portions of the corner brackets 9 and are confined by vertical bolts 12 passing through said loop portions of the corner brackets. The lower ends of the springs 11 rest upon my improved transverse supporting member which is mainly shown in detail in Figs. 2 and 3, and which will now be described. The said transverse supporting member comprises a pair of end pieces each designated as an entirety by 13, and an intermediate bar 14 that is detachably and adjustably secured to the inner ends of the end pieces 13 and connects the latter. Each end piece 13, more particularly described, comprises an outer substantially flat portion 15 that rests directly upon the side rail 6 of the bed-stead frame, an intermediate shallow cup-shaped portion 16 that forms a seat for the lower end of the spring 11, and an inner shank portion 17 that is provided with a shallow socket 18 which snugly receives and fits the end of the connecting bar 1 1. The vertical wall of the shank member 17 is formed with a horizontal slot 19 that receives a fastening bolt 20 passed through the end of the connecting bar 141. By means of said bolt and the socketed shank of the end piece, the latter and said connecting bar are securely and strongly united with capacity for relative longitudinal adjustment to the extent of the length of the slots 19. On the under side of the end piece 13 is preferably formed a lug 21 that abuts against the inner edge of the side rail 6 and serves to prevent longitudinal displacement of the complete transverse support.

Where the transverse support, in bed-bottoms of this type, consists, as heretofore, of a single member, it interferes with and prevents the nesting together of two bed-bottoms which is a desirable expedient for purposes either of storage or shipment, as considerable space is thereby saved. By means of my improvement, for purposes of storage or shipment the intermediate connecting bar 14: can be readily taken out, and two bed-bottom frames can be nested together with their fabric sides outermost and with their longitudinal side rails and corner brackets lying side by side. Furthermore, my invention provides a transverse support that s readily adjustable to limited variations in Width of bed-stead frames, and one in which the engagement of the lugs 21 With the side rails of the bed-stead frame can always be insured.

I claim 1. A support for bed-bottoms adapted to span the side rails of a bed-stead frame, comprising a pair of end pieces each having an outer portion adapted to rest directly on the side rail, an intermediate spring-seat, and an inner shank portion, and an intermediate bar detachably secured to and connecting the shank portions of said end pieces, substantially as described.

2. A support for bed-bottoms adapted to 15 ing an outer portion adapted to rest directly on the side rail, an intermediate spring seat,

and an inner socketed shank portion, and 20 an intermediate bar detachably and adjustably secured to and connecting the socketed shank portions of said end pieces, substantially as described.
